 of a rusty red, and upon these parts there 

 are white spots and stripes, of the arrange- 

 ment of which the illustration will give a 

 better idea than a long description. The 

 horns of the male are thick, flattened, and

provided with two keels or ridges, which 

 meet at the extremity of the horn. The 

 two horns have an elegant curve inwards. 

 This beautiful animal lives in pairs in the

 pretty well, and on account of its gentleness
